The values in the table below have been grouped based on the Y-DNA test results
and available genealogies, paying particular attention to the guidelines set
forth by FamilyTree DNA in the following documents concerning
"Interpreting Genetic Distance" in the
12-marker,
25-marker,
37-marker and
67-marker tests. The darker shaded boxes within a group
indicate a value difference from the most common value.

You can click on any kit number in the left-most column to bring up a window
with the corresponding genealogical information and contact email addresses.

Haplogroups in red have been predicted by Family
Tree DNA based on unambiguous results in the individuals' personal page. Please
note that for any predicted results we see no reason for ordering a SNP test to
confirm the Haplogroup. If a blank space is in the HAPLO field then we feel
that the comparative results are not clear and unambiguous and if the kit
holder wants to know their SNP with 100% confidence they may consider ordering
a SNP confirmation test.

DYS 19 is also known as DYS 394.

It is obvious from our observation of 1000's of samples that some markers
change or mutate at a faster rate than others. While that actual 'faster rate'
has not yet been definitively calculated, not all markers should be treated the
same for evaluation purposes.

The markers in red have shown a faster mutation
rate then the average, and therefore these markers are very helpful at
splitting lineages into sub sets, or branches, within your family tree.

Explained another way, if you match exactly on all of the markers except for
one or a few of the markers we have determined mutate more quickly, then
despite the mutation this mismatch only slightly decreases the probability of
two people in your surname group who match 11/12 or even 23/25 of not sharing a
recent common ancestor.
